Project Description
Goshen Community Schools were awarded zero-interest Qualified School Construction Bonds in 2009 and decided to take advantage of the opportunity to upgrade their existing building systems. They partnered with Performance Services to implement a guaranteed energy savings project. Existing systems included original equipment past it expected useful life and obsolete pneumatic controls that were highly inefficient and failed to function properly. Prior to the renovation, teachers resorted to manually turning off unit ventilators in an attempt to control classroom noise and temperature issues.
Following three phases of renovation and controls work with Performance Services, the school corporation has classroom environments conducive to learning and no longer need to manually operate controls to reduce noise levels and room temperatures.
In 2018, Performance Services completed a district-wide Facility Master Plan which included mechanical, electrical, and plumbing improvements along with roof work. This led to four more phases of construction to continue to upgrade the school district’s energy systems to make them more efficient and reduce energy costs.
